d1.11
V/F slip compensation gain
Range:0.0
～
300.0%
Default: 80.0%
This parameter is valid only for the asynchronous motor.
It can compensate the rotational speed slip of the asynchronous motor when the load of the motor
increases, stabilizing the motor speed in case of load change.
d1.12
Stator voltage drop
compensation gain
Range:0.0
～
200.0%
Default:100.0%
Stator voltage drop compensation is to compensate voltage drop produced by stator resistance
and connecting cable.
d1.13
Excitation boost gain
Range:0.0
～
200.0%
Default:100.0%
d1.14
Oscillation Suppression
Range:0.0
～
300.0%
Default: Model
defined
Set this parameter to a value as small as possible in the prerequisite of efficient oscillation
suppression to avoid influence on V/F control. Set this parameter to 0 if the motor has no oscillation.
Increase the value properly only when the motor has obvious oscillation. The larger the value is, the
better the oscillation suppression result will be.
When the oscillation suppression function is enabled, the rated motor current and no-load current
must be correct. Otherwise, the V/F oscillation suppression effect will not be satisfactory.
d1.15
Voltage source for V/F separation
Range:0
～
7
Default: 0
d1.16
Voltage digital setting for V/F
separation
Range:0.0
～
100.0%
Default:0.0%
V/F separation is generally applicable to scenarios such as induction heating, inverse power
supply and motor torque control. If V/F separated control is enabled, the output voltage can be set in
d1.15 or by means of analog, multi-reference, simple PLC, PID or communication. If you set the output
voltage by means of non-digital setting, 100% of the setting corresponds to the rated motor voltage. If
a negative percentage is set, its absolute value is used as the effective value.
0: Digital setting (d1.16)
1: Keypad potentiometer (When using LED keypad)
2: AI1
3: Multi-reference
4: Pulse setting (DI7/HI)
5: PID
6: AI2
7: AI3 (VSX Only)
d1.17
Voltage rise time of V/F
separation
Range: 0.0
～
6000.0s
Default:0.1s
This parameter value is the time rising from 0V to motor rated voltage or dropping from rated
voltage to 0V.
d1.18
Set the IQ filter time below
0.5Hz in VVF mode
Range: d1.19
～
3000ms
Default: 500ms
d1.19
Set the IQ filter time above
2.0Hz in VVF mode
Range: 1ms
～
d1.18
Default: 100ms
d1.18~d1.19 set the current filter time of torque
d1.20
Torque revision when run
forward
Range: 0.0~5.0%
Default: 0.0%
d1.21
Torque revision when run
reverse
Range: 1ms
～
d1.18
Default: 1.0%
d1.20~d1.21 set the revision coefficient of torque.
